VC++ 5.0 is years out of date. The price of the standard version of 7.0 is 
$99. Please don't make library decisions based on what 5.0 will or won't 
do!

I wrote some accounting software once for a petroleum distributor. Price 
(dollars per gallon, 4 places) times quantity (in gallons, 1 place) yielded 
invoice amount (in dollars, 2 places).

If the product was propane, the quantity was first adjust by temperature 
differential (in degrees, 0 places) multiplied by expansion factor (pure 
number, can't remember how many decimal places it was carried to.)
